LED spotlight is a kind of lamp whose illumination on the illuminated surface is higher than that of the surrounding environment, that is, looking up. Usually, it can aim in any direction and has structures that are not affected by climate conditions. The shell of high-power LED spotlight produced by Yugao Hardware and Electrical Appliances has reached IP66 protection level, that is to say, it can completely prevent foreign objects and dust intrusion in dust prevention, and in water-proof and moisture-proof aspects: it can prevent the invasion of large waves, it can be installed on the deck of ships, and it can prevent damage caused by the invasion of large waves.
LED projection lamp is mainly used for large-area factory, mine, building outline, stadium, overpass, monument, Park and flower beds for building decoration lighting, and commercial space lighting to create a good projection effect. The decorative component is heavy, and its appearance is round and square. The patch LED is mostly driven by low voltage and uses aluminum substrate to dissipate heat, so its lamp shell mostly uses aluminium alloy, because the proportion of aluminium alloy is 2.7, much smaller than that of iron and copper, that is to say, the overall weight is lighter. Aluminum alloy has good heat dissipation effect, high-reputation design of LED projection lamp shell, large heat dissipation surface area, reasonable heat dissipation structure, good overall heat dissipation of lamps, can reduce the probability of failure, thus ensuring the design life of LED projection lamp. The design of internal and external anti-seismic structure effectively solves the problems of bulb falling off, bulb life shortening and bracket breaking caused by strong vibration.
The output beam angle of Yugao LED projection lamp is 130 degree symmetrical wide angle light distribution system. High purity aluminium reflector, precise beam and best reflection effect are adopted. Replacement of light bulbs, easy maintenance. The optical characteristics of LED lead to glare problem. It needs a good light transmission lampshade to form a surface light source to a certain extent.
At present, the commonly used LED spotlights on the market are basically 1W high-power LED. Each LED component will have a high-efficiency lens made of PMMA. Its main function is to redistribute the light emitted by the LED, that is, secondary light. With high efficiency gas discharge lamp as light source, the lamp has a long service life of more than 10000 hours, especially suitable for outdoor large area unattended lighting. It has good electromagnetic compatibility and will not cause electromagnetic interference to the surrounding environment.
